1. Страшно и опасно! Данните ни са все по-уязвими от хакерските атаки.

   %Robert Harmon: Надявам се, че полските железници вземат подходящи мерки за защита от тези хакери.

   %Anna Chapman: Това е още един пример за застрашаване на нашата сигурност и инфраструктура от кибератаки. Трябва да се инвестира в киберсигурност.

   %Marko Petrov: Полските железници трябва да бъдат много внимателни със защитата на техните системи от хакери.

2. By way of explanation, Charles Darwin’s theory of evolution states that over time, species undergo changes to adapt to their environment, which increases their chances of survival and reproduction. This theory is based on the concept of natural selection, which means that individuals with traits that are advantageous for survival are more likely to survive and pass on those traits to their offspring.

   Darwin observed that within a population, there is variation in traits and that some traits are more beneficial than others in a given environment. For example, in a population of giraffes, some individuals may have slightly longer necks than others. In an environment where the main food source is high up in the trees, having a longer neck would be advantageous as it allows the giraffe to reach the food more easily. Over time, the giraffes with longer necks are more likely to survive and reproduce, passing on their long-necked trait to their offspring. This leads to an increase in the proportion of giraffes with longer necks in the population.

   Additionally, Darwin emphasized that evolution happens gradually and through small, incremental changes. It is not a sudden transformation but a gradual process that occurs over many generations. This concept is known as gradualism.

   Furthermore, Darwin’s theory of evolution is supported by evidence from various fields, including fossil records, comparative anatomy, embryology, and molecular biology. Fossils provide a record of past life forms and show how species have changed over time. Comparative anatomy studies the similarities and differences in body structures between different species, which can indicate common ancestry. Embryology examines the development of organisms from fertilization to birth, revealing similarities in early stages of different species. Molecular biology looks at the genetic similarities and differences between species, providing evidence for common descent.

   Overall, Darwin’s theory of evolution provides a comprehensive explanation for the diversity of life on Earth, emphasizing the role of natural selection in shaping and changing species over time. It is widely accepted in the scientific community and forms the basis of modern biology.

3. Ows the giraffe to reach the food more easily. Over time, individuals with longer necks would be more likely to survive and reproduce, passing on their longer neck trait to future generations. This process, known as natural selection, can lead to the evolution of a population over time.
